History Characters / ResidentEvil4

* TheHeart: Luis in the 2023 remake of ''4'' plays a more substantial role in Leon, Ashley and Ada's stories, helping them pull through in their darkest hours and effectively becomes the glue that holds each of them together long enough make it out alive, [[spoiler:even though he himself doesn't make it to the end]].

* CasanovaWannabe: He claims to be "quite the ladies' man", but Ashley's not really impressed with his attempts at being smooth, and neither is Ada. Downplayed with Ada in the remake of ''Separate Ways'', who indulges Luis when he amorously grabs her for an impromptu tango and plays along with him for a bit despite rolling her eyes at the gesture.

* CasanovaWannabe: He claims to be "quite the ladies' man", but Ashley's not really impressed with his attempts at being smooth, and neither is Ada. Downplayed with Ada in the remake of ''Separate Ways'', who does at least humor Luis when he amorously grabs her for an impromptu tango, playing along with him for a bit despite rolling her eyes at the gesture.

* CasanovaWannabe: He claims to be "quite the ladies' man", but Ashley's not really impressed with his attempts at being smooth, and neither is Ada.

* AscendedExtra: While still an important character, Luis was largely forgotten after Saddler kills him, and played a role in the original Separate Ways. In the remake of 4 and Separate Ways, he plays a much larger role by subduing Leon, Ashley, and Ada's infections, went to grab the Master Plagas for Ada, and even Wesker needed him alive. He is also an AssistCharacter fighting with Leon and Ada in separate sections, and giving him more things to do before he bought the farm.

** In the original, Krauser sought after Wesker due to his CareerEndingInjury that cost his left arm, and he was fired for it. Wesker takes him in and has him infiltrate the Los Iluminados so Wesker can obtain a Las Plagas sample but he is able to get it through his corpse. In the remake, Krauser has no such relationship with Wesker and joins the Los Iluminados on his own.

* MightMakesRight: In a similar vein to [[Franchise/DevilMayCry Virgil]], Krauser's dialogue in the remake is ''littered'' with obsessions of gaining power and how that it's the most important thing in the world, and that those without power can't protect or save anyone, let alone themselves.

A former elite US soldier who defected from the government after Operation Javier and now works for Los Iluminados as Saddler's enforcer. He personally carried out the kidnapping of Ashley Graham, and has history with Leon.

* AchillesHeel: Unlike other enemies, Krauser takes an incredible amount of damage from the knife. It's an effective strategy to simply knife him to death in boss fights. This effect is not present in the remake however.

** In the original, Krauser sought after Wesker due to his CareerEndingInjury that cost his left arm, and being fired for it. Wesker takes him in and has him infiltrate the Los Iluminados so Wesker can obtain a Las Plagas sample, but was able to get it through his corpse. In the remake, Krauser has no such relationship with Wesker and joined the Los Iluminados on his own.

* AdaptationalBadass: In the remake, [[spoiler:his final boss fight has his other arm mutated as well in addition to his left BladeBelowTheShoulder]].

* CloseRangeCombatant: His primary schtick in ''The Mercenaries'' (remake version). His kit is tailored towards close-quarters crowd control, with little sniping options for long range threats, but more than makes up for it by being a LightningBruiser who can take more hits than anyone else and has special melee attacks akin to hack-and-slash combat with his unbreakable knife. His Mayhem Mode also mutates him into an unflinching demon that can kill even mini-bosses with just two or three hits from his oversized arms, plus a finisher that instantly pulverizes everything in his path.

* CombatPragmatist: His second boss fight takes place on a battlefield he's littered with traps and gun-mounted drones, showing he's pulling no stops when testing Leon. He also halts their banter before the fight by blasting Leon with a machine gun he'd been hiding behind him.

** Heavily {{Downplayed|Trope}} in the remake, where their past partnership has been significantly overhauled. Krauser was actually Leon's drill sergeant instructor and superior officer, and Leon always thought of him as a {{Jerkass}}, but nevertheless, still respected and admired him in someway, and is extremely shocked and bitter with his betrayal.

** In the original game, they didn't even request for him to join up with the organization to stop bioweapon threats, yet they allowed Leon to join, and later their firing him because the Javier mission had him injured in his arm with it not fully recovering.

* MagicPants: While his arms get torn up after transforming in the Mercenaries, his gloves remain undamaged.

* NervesOfSteel: Subverted in Darkside Chronicles. While Krauser seems cool under the collar in the main game, the bonus mode told from his point of view reveals him cracking under pressure. Not only does he plead for Leon to save him, he slowly descends into madness and develops a sick fascination with the viruses' power.

* PetTheDog: Has two notable ones in the remake.

* RedAndBlackAndEvilAllOver: His attire is mostly dark shades with red for accents, like his beret. He even dons red warpaint in his final battle. It also provides contrast between him and Leon who wears a lot of blue throughout the series.

* ShellShockedVeteran: Krauser feels he is useless outside of the battlefield, and that being a soldier is his calling, to the extent that he often underwent mercenary missions even when he was off-duty from SOCOM. This is a large part of the reason why he ultimately turned to Wesker's help after [[spoiler:the US Government fired him due to his arm injury never really recovering.]] This backstory carries over to the 2023 remake in a different fashion. Krauser's comments about what transpired during that universe's iteration of ''Operation Javier'' indicates that he was horribly traumatized by whatever wiped out his men, causing him to become fixated on becoming strong, no matter how much of his humanity he had to sacrifice.

** In the original he only showed up a few times before [[spoiler:being killed by Saddler]], with little being revealed about his past outside of how he used to work for Saddler. The remake gives him an expanded backstory as a former Umbrella researcher and a more developed friendship with Leon, making him effectively part of the main cast. He also [[spoiler:dies considerably later in this version, only meeting his end in the first Krauser encounter]]. The remake's version of ''Separate Ways'' further expands Luis' character by making him a prominent supporting character in Ada's campaign, as opposed to a single cutscene appearance in the original.

[[spoiler:He also dies considerably later in this version, only meeting his end in the first Krauser encounter.]]
** [[spoiler:In the remake, a notebook can be found in the cave where Leon first meets Luis. It recounts a man raising his grandson within the woods, who's highly implied to be Luis due to his interest in ''Don Quixote''. The notebook prematurely ends with the man ending up sick from a wolf bite, fearing whatever will happen to his grandson when he's alone; the wording implies he may have died from Las Plagas. Another set of notes found later on reveals that the tale ultimately ends with the grandfather's cabin in flames, with the author recounting that the boy disappeared the next day.]]

* CaptainObvious: At one point in a radio call with Leon, Salazar asks with deadly seriousness (assmuning he did not mean "without serving some purpose"): "Did you know no one dies without a cause?"

* CaptainObvious: At one point in a radio call with Leon, Salazar asks with deadly seriousness: "Did you know no one dies without a cause?"

* ColdHam: In contrast to the loud, screaming bombastic and theatrical orignal, the remake Salazar is calm, polite and genteel, with the malice of every polite whisper cold enough to turn the blood in your veins into ice.

* DeathTrap: His castle is chock full of them, from [[SpikesOfDoom spiked pits]] to [[TheWallsAreClosingIn closing walls]], making it actually more dangerous

* FauxAffablyEvil: In contrast to the original where he constantly belittles Leon with screaming tantrums and childish insults, Salazar in the remake is a cordial gentleman who consistently addresses Leon with genteel respect, even going as far as to warmly insist "Please, call me Ramon" during their introduction, never losing his cool until the agent fills him with bullets, causing the gentleman to ''literally'' explode [[OneWingedAngel into the savage monster that he really is inside]].

* {{Foil}}: To Bitores Méndez. While Méndez was a rather serious character and his encounters with Leon were typically rather frightening, Leon's encounters with Salazar tend to be rather humorous. While Méndez was typically rather cold and unfeeling, Salazar is gleefully sadistic. Méndez was [[TheQuietOne a man of few words]], while Salazar ''loves'' hearing himself talk. Méndez fought Leon himself after deliberately setting a trap for him, but Salazar fights Leon as a last resort, with the help of his bodyguards and a giant plant monster. Finally, while Méndez initially decided against killing Leon himself due to him possessing a Plaga, Salazar is quite eager to do so.

** Despite Ashley being the crux of Saddler's entire EvilPlan to TakeOverTheWorld, Salazar on more than one occasion tries to have her killed rather than captured. This changes in the remake, where he specifically tells his goons not to harm her.

* ObliviouslyEvil: Sort of. He definitely takes glee in using his death traps, but his diary reveals Los Iluminados fed him lies about what exactly Las Plagas was and painted his heroic ancestor as a bad guy who was persecuting them. He felt the need to unleash them as [[TheAtoner atonement for this]]. Having been infected by Las Plagas himself, it's hard to say how he ''really'' feels now. Subverted in the remake, where his revamped backstory describes him as having long been a depraved, sadistic freak before he even joined Saddler's cult.

* PsychopathicManchild: He has zero self-control in the original game and throws tantrums whenever things go wrong for him. He's initially much more composed in the remake, but the BossBattle with him (and subsequent notes on his past) clearly show that deep down he very much is an unhinged, childish monster.

* UsedToBeASweetKid: Formerly a benevolent young castellan before Saddler's manipulations and Las Plagas infection turned him evil. This is averted entirely in the remake, where Salazar was described as irredeemably vicious and cruel long before Los Illuminados came back into the picture.

** Leon always keeps a cool head when talking down Salazar despite the villain's best efforts to try and get under Leon's skin, and that drives him ''insane''.

* YoungerThanTheyLook: Though still youthful-looking, facial-wise, Salazar's Plagas infestation caused his hair to prematurely turn gray and his skin to look deathly pale, giving Leon the impression that he's an old man despite only being twenty years old. The effect is even more pronounced in the remake, where he actually looks like a wrinkly geezer.

** His exposed spine is a weak point in the first half of the battle, while the shotgun is an excellent way to knock him down from the rafters in the second stage.

** In the remake, his first phase weak spot is now an eye on his back. Given his posture, that means shooting down at him from the second level of the barn.

* BewareTheQuietOnes: He only speaks to Leon once in the entire game. He gets more lines in the 2023 remake, but is still portrayed as a quiet threat.
* BondVillainStupidity: He nearly strangles Leon to death, but lets him go when he sees he's been injected with a Plaga egg, knowing that he'll eventually succumb to the parasite's control. He later admits in a memo that he gravely [[UnderestimatingBadassery underestimated Leon's capabilities]] and that at the rate he's going, he'll probably destroy the whole village before the Plaga takes over. [[DownplayedTrope Downplayed]] however, in that if Leon tries to follow him he won't show the same mercy as before and it's only the timely intervention of Ada that saves Leon.
* TheBrute: Compared to the other villains in the game, Méndez relies purely on brute strength, which gives Leon trouble in the early sections of the game.

* NoNonsenseNemesis: Unlike Saddler or Salazar, Méndez takes far less chances with Leon, swiftly knocking him out the first time they meet and only sparing him on Saddler's orders. Even then Méndez still would have killed him in their next encounter if he hadn't noticed Leon was infected. It's probably a good thing for the player he was only in charge of the village.
* OneWingedAngel: Resembles some manner of monstrous praying mantis.

* TheStoic: He remains very stone-faced, even while dealing with Leon one-on-one. Though he does start to crack a bit once you've gotten to the second phase of his boss battle.

* AdaptationalPersonalityChange: He was originally a more stoic antagonist, only becoming more deranged after his transformation. In the remake, he's an openly sadistic and maniacal villain even before he transforms, taunting and berating Leon in all sorts of ways.

* AlasPoorVillain: His [[spoiler:death is portrayed much more mournfully in the Remake than the original, being framed as a MercyKill towards a long-broken soldier.]]

* BaritoneOfStrength: Creator/JimWard portrays him with a deep and gravelly voice to match his imposing stature and skill with a knife. This isn't the case in the remake, which instead gives him a higher-pitched tenor voice.

** Heavily {{Downplayed|Trope}} in the remake, where their past partnership has been significantly overhauled. Krauser was actually Leon's drill sergeant instructor and superior officer, and Leon always thought of him as a {{Jerkass}}, but nevertheless, still respected and admired him, and is extremely shocked and bitter with his betrayal.

* {{Jerkass}}: Leon's comments imply Krauser's always been a bit of an asshole, having been a domineering presence during their time as comrades. And turning Heel has dialed up those traits, making him cold and condescending towards everyone he faces.

* MadeOfIron: He takes a staggering amount of punishment from Leon's guns before finally going down for the count. And even ''that'' wasn't quite enough (at least, in the original game) since his badly mangled body still manages to spring back to life for one last fight, this time against Ada.

* NotQuiteDead: [[spoiler:In the original, Leon apparently kills him and leaves his corpse to be blown up by his own explosives. He manages to survive the explosion, though horrifically burned in the process. Ada makes sure to finish him off, so there won't be any loose ends to deal with]].

* RivalTurnedEvil: ''Darkside Chronicles'' lays out the rather tragic story. Leon and Krauser only knew each other for one mission, but they earned each other's respect and friendship and from Leon's point of view, parted as friends. [[BeneathTheMask In reality]], because of a combination of the insane stress of the mission, fear of rejection by the government after a major injury, and subsequent desire for power with which he could liberate himself from others' control, Krauser sought after organic weaponry to augment himself immediately after that mission, breaking all bonds with Leon and the US government (although the fact that the US government fired him because of his injury was probably a huge factor in that last part of his viewpoint).

* SillyRabbitIdealismIsForKids: His fight banter with Leon has heavy shades of this with him insulting Leon's viewpoints of right and wrong and how he always tries to save everyone.

* SuperMode: In the remake, his Plaga transformation becomes a triggerable change in Mercenaries, granting him a few seconds where he can tear apart enemies with empowered melee strikes.

* WorthyOpponent: In the remake, his battle dialogue suggests he considers Leon this, with him saying he is grateful to the US for sending Leon instead of some "good-for-nothing grunt".

** Also in the original, Saddler had him pegged for a rat all along, and fully planned to dispose of him once he'd served his purpose. This dynamic is absent in the remake due to Krauser no longer being TheMole for Wesker.

* AdaptationalVillainy: And to complete the changes in his character, Saddler’s plan '''much''' more ambitious in the 2023 remake. In the original, Saddler is a self-aware scummy arms dealer using his religion in an obvious con and it’s clear he doesn't believe a word of it, using Los Iluminados to facilitate a power grab. In the remake, he’s a true believer and Saddler fully intends to use Ashley as the first step to infecting the entire world with him as a savior "from the tyranny of free will".

* AdaptationalNiceGuy: While she was [[DownplayedTrope still]] a NiceGirl in the original, she would have moments of occasional brattiness toward Leon such as pushing him away after she coughed up blood. In the remake, she is much less bratty and does her best to help Leon out however she can.

* ButtMonkey: In the original game, she gets kidnapped three times, terrorized by armored plagas, and Leon makes jokes at her expense. Heavily downplayed in the remake where her victimization is taken very seriously, and Leon has to calm her down when she panics.

* CowardlyLion: She is by no means an ActionGirl like the majority of playable female characters in the franchise and this is reflected by her being completely terrified of the situation she’s in. Nonetheless, she will brave through the storm if it will save her own skin and Leon’s. This personality trait of hers is more pronounced in the remake as she saves Leon’s life several times.

* DemonicPossession: Has a moment in the remake where she loses consciousness in Leon's arms, only to to wake up apparently possessed by Saddler, threatens him with a knife, and [[PsychicAssistedSuicide then holds it to her own throat]] to separate her from Leon before he releases control.

* GrewASpine: Her character arc in the remake. While she understandably needs rescuing from a village of cultists, she's encouraged by Leon to not give into fear or despair. In time, she becomes more proactive, not just in defending herself, but actively finding ways to help Leon as well. By the end, she's an ActionSurvivor who even hints at an interest in making the jump to full on trained ActionGirl. Her voice lines when being abducted by a random enemy transition from being fearful and desperate during most of the game to willfully resistant and almost irritated after rescuing her from her cell near the end of it.

* NiceGirl: Occasional brattiness aside, she’s a sweet girl who does her best to help Leon whenever she can, with this aspect of her personality being more pronounced in the remake and her occasional brattiness being heavily downplayed.

* OneHeadTaller: Leon is this to her, but certain enemies are this to him. The size difference [[https://i.imgur.com/nEA0i0F.jpg between Ashley and the Zealots]] in her chapter are quite noticeable.

* VideoGameCaringPotential: Depending on your take on {{Escort Mission}}s, Leon can either be nice to her or [[VideoGameCrueltyPotential an absolute jerk]].

* AdaptationNameChange: Originally just "Luis Sera." In the remake, his name is extended to "Luis Serra Navarro". Since in Spanish-speaking countries people have two surnames (the second one being their mother's maiden name), this is more coherent. As a minor example, he pronounced his name in the original correctly as [=Lew-EEz=], but Leon would always call him Lew-IZ, which led to many fans following suit. The remake has the entire cast use the former instead.

* EmpoweredBadassNormal: He was once a host to a Plagas, giving him inhuman durability. He may have also once been a police officer in Madrid, which explains his skill with firearms, but alongside the likes of Leon and Ada (who are both highly trained special agents), it's easy to forget that Luis is just a fairly normal scientist in comparison.

* GoodOldFisticuffs: Compared to trained characters' movesets like Leon and HUNK's snappy manuevers, Luis's melee attacks in the ''Mercenaries'' mode are rather unrefined, consisting of awkward shoulder tackles and sloppy kicks.
* GoOutWithASmile: [[spoiler:In the remake, Luis died from his fatal knife stab while letting out a small smile, believing that people like him can change for the better.]]

* MadeOfIron: One may presume it's due to once being host to a full Plagas. During the siege on the cabin, the player can shoot him several times (on purpose or accident), this does little but annoy Luis, [[VideoGameCrueltyPunishment until he has enough and calmly kills Leon with just a couple shots]], though only in the original game since he never resorts to that in the remake.

* NiceGuy: Lecherous comments aside, he is one of the nicest people in the series. He genuinely wants to help Leon and Ashley, and willing to go out of his way to do so. He's also [[spoiler:trying to undo the events he helped set in motion]]. His genuine good will [[spoiler:is even what freed him from Saddler's control (see HeroicWillpower above)]].

* PreAssKickingOneLiner: Gives one before the HoldTheLine mission:

* TrustPassword: In the remake, Luis was going to [[spoiler:give the Plagas Amber to Ada in exchange for help escaping Los Iluminados, and the two used cigarettes as a sign and countersign. When he asks Leon for a smoke, Leon gives the wrong answer, which makes Luis realise he's not his contact]].

* WeakButSkilled: Compared to the super soldiers and secret agents he's flanked by when it comes to the Mercenaries' cast, Luis is just a normal guy who at most might have had some police training, and it's reflected by his unremarkable melee moves. He nonetheless has enough experience with firearms, explosives and lead pipes to hold his own.

-> ''"Yeah, swiped 'em clean!"''\\\

* MythologyGag: [[spoiler:His death in the remake is by a swarm of Novistadors causing his helicopter to crash, which is an allusion to Saddler's quote in the original game of killing Mike on the level of "swatting a bothersome fly".]]

* WeHardlyKnewYe: He shows up [[spoiler:for one level before being shot down and killed off]].

* AdaptationalNiceGuy: {{Downplayed|Trope}}. He was never a "jerk" in the original game per se, but maintained a strictly professional relationship with the playable characters. In the remake, however, completing all of his challenges gets him to call Leon a "friend" rather than his trademark "stranger", which shows that the Merchant holds him in a higher regard this time. Much like his pal [[VideoGame/ResidentEvilVillage The Duke]], he's also shown to be more talkative and considerably friendlier than his original counterpart, engaging in plenty of (one-sided) banter whenever Leon stops by.

* IntrepidMerchant: No matter how far you go, he'll always be ahead of you to sell his wares.

* TheSpook: The Merchant is incredibly enigmatic because the game doesn't really acknowledge his presence as a character. No one directly speaks to him or even pays much attention to him, enemies ignore him, and he doesn't play any real role in the overarching narrative. The closest the remake comes to changing it is having Leon ask himself who he is upon meeting him for the first time, and Ashley indirectly acknowledging him while asking if Leon intends to sell a specific treasure he finds in the castle. He's just this odd guy with a pirate accent who doesn't seem to have any stake in the Los Iluminados conflict (except it giving him an opportunity to move some merchandise). He does get acknowledged by the Duke in ''Village'' when you buy his wares and is mentioned as an old friend who used to say "What are you buying?".

* VideoGameCrueltyPotential: You can show your "appreciation" towards the Merchant's high prices by slashing him with your knife or shooting him, which will kill him on the spot. Although he will continue to appear later in the game, even on Professional difficulty, meaning you can murder him to your heart's content on all difficulty settings. The remake, on the other hand, makes him unkillable.

* WillOTheWisp: Inverted, in the sense that the light leads you towards safety. His various campsites are marked from a distance by a strong, blue flame that contrasts the darker environments. At one point, when Ada meets him during the course of ''Separate Ways'', he considers his shop incomplete without it. In the remake, he has both a blue-flamed latern and the larger lamp burning a purple flame. [[spoiler:What's implied is that another reason the Plagas don't bother the Merchant is because of the blue-flamed lantern, the same type that Ashley can use to immobilize the Armaduras Leon has to fight to get the Lion Head in the remake.]]

* DiesDifferentlyInAdaptation: In the remake, he's found murdered by the first villager encountered in the game. His corpse is later decapitated and fed to Del Lago.

* RedShirt: A nameless cop in a ''Resident Evil'' game? Yep, he's gonna die pretty quick.

--> '''Saddler:''' (makes a "Guess I walked into that one." laugh)
* AdaptationalBadass: Saddler gains a [[spoiler:second transformation in the 2023 remake, where he is surrounded by several giant tentacles which prevent Leon from getting close to him. He also manages to survive the rocket launcher and is only really finished when Leon impales him through the eyeball with his own staff]].

* AdaptationalNiceGuy: A downplayed example, since he's still a murderously twisted man in the 2023 remake, but now framed as a WellIntentionedExtremist. The original game implied that he didn't truly believe in the teachings of Los Iluminados and was more interested in accumulating power and taking over the world. The remake has him claiming that he wants to spread Las Plagas because he wants to bring peace and unity to a world that he sees is filled with hate and suffering. As a result, the remake's version of Saddler does not share the original incarnation's bigotry against Americans.

* AffablyEvil: The remake portrays him as a much more cordial, but still very malicious, being who sees the Plaga as a twisted means to unite the world. He almost never raises his voice against Leon and Ashley, even after Leon has just shot him in the head, and constantly tries to bring them to his side. This attitude eventually crumbles by the final battle, where he's become enraged at Leon's constant thwarting of his attempts to spread the Plaga.

* DeadpanSnarker: Surprisingly for a horrifying cult leader, Saddler carries himself wth a laid back and sarcastic attitude. His conversations with Leon can best be described as snark-offs compared to the more volatile exchanges with [[NoNonsenseNemesis Bitores]] and [[IneffectualSympatheticVillain Salazar]]. Less so in the remake, where Saddler is portrayed as a much more serious villain.

* FauxAffablyEvil: When Leon makes quips at his expense, Saddler always responds with a good-natured chuckle before telling him in a conversational tone how Leon will not succeed, and usually keeps from sounding agitated when Leon goads him. Even when Leon manages to rescue Ashley at the Island after being cured of Las Plagas via the Plagas Removal Laser, Saddler's only reaction is to express amusement at him for managing to foil his plans before transforming. This, of course, does not change the fact that he is a depraved, megalomaniacal cult leader who has infected scores of innocent people with his personality-altering Las Plagas parasites. Downplayed in the remake which opts for a more classic AffablyEvil attitude; he even seems genuinely upset when his minions in his FlunkyBoss form die.

* FlashStep: He's quite fond of using this during his boss fight with Ada. Unlike Wesker, he doesn't use it to [[DodgeTheBullet dodge bullets]].

* ImmuneToBullets: In the original game, when Ada pours several machine gun bullets into him, it merely stuns him for a few seconds, after which he ejects all the bullets out of his hands. In the remake, the same thing happens, [[spoiler:though Ada actually succeeds in briefly incapacitating him before he recovers and overpowers her off-screen]].

* LastNameBasis: No one calls him Osmund.

* OneWingedAngel: The final battle against him has Saddler transform into a spider-like monstrosity, with his own face becoming a monstrous claw with an eyeball inside his mouth. He gains a [[spoiler:second transformation in the 2023 remake, where his already bulky body grows to truly gargantuan size, gaining more tentacles while becoming stationary]].

* PoliticallyIncorrectVillain: Makes it quite clear he is not fond of Americans. Inverted in the remake, where he states that he plans to unite people of all races, nations and creeds in his planned utopia, without any prejudice.

* SuddenlyVoiced: The remake has him still able to talk in his OneWingedAngel form with a VoiceOfTheLegion.

* AdaptationalBadass: In the 2005 game, Ramón never displays any kind of power from his Plagas infestation besides having command over the many dangerous mutants that reside in his castle, and it takes fusing with a giant, stationary monster plus one of his Verdugos for him to even have the guts to face Leon in direct combat. His 2023 self, in contrast, is fully capable of transforming into a stronger, monstrous form on his own, which also grants him enhanced speed and spider-like mobility. This difference in strength is reflected in how the two Salazars react to injury: the 2005 version starts whimpering and flees after Leon throws a knife that impales his hand, whereas the 2023 version becomes incensed when Leon shoots him thrice, not once cowering. To go with this, Salazar is treated as a genuine threat in the remake as opposed to being treated as a joke in the original.

* AdaptationalVillainy: Downplayed in the remake, as Salazar is already an unpleasant guy to begin with, but the memos you get across the castle imply that he's already an asshole in-and-out even before Saddler entered the scene and being infected with the Plaga, as opposed to the original where he was a lot more composed in the past.
* AintTooProudToBeg: In the remake, [[spoiler:when he is moments away from death, Ramón screams out and pathetically begs his master, Lord Saddler, to save him.]]

* AdaptationalNiceGuy: {{Downplayed}}. He was never a "jerk" in the original game per se, but maintained a strictly professional relationship with the playable characters. In the remake, however, completing all of his challenges gets him to call Leon a "friend" rather than his trademark "stranger", which shows that the Merchant holds him in a higher regard this time. Much like his pal [[VideoGame/ResidentEvilVillage The Duke]], he's also shown to be more talkative and considerably friendlier than his original counterpart, engaging in plenty of (one-sided) banter whenever Leon stops by.

* EvilOverlord: {{Downplayed}}. His authority doesn't extend much beyond Pueblo and Salazar's castle. Still got the hordes of monsters and world-conquering ambitions, though.

** Heavily {{Downplayed}} in the remake, where their past partnership has been significantly overhauled. Krauser was actually Leon's drill sergeant instructor and superior officer, and Leon always thought of him as a {{Jerkass}}, but nevertheless, still respected and admired him, and is extremely shocked and bitter with his betrayal.

* AdaptationalVillainy: And to complete the changes in his character, Saddler’s plan '''much''' more ambitious in the 2023 remake. In the original, Saddler is a self-aware scummy arms dealer using his religion in an obvious con and it’s clear he doesn’t believe a word of it, using Los Iluminados to facilitate a power grab. In the remake, he’s a true believer and Saddler fully intends to use Ashley as the first step to infecting the entire world with him as a savior “from the tyranny of free will”.

* BigBadWannabe: He’s ultimately little more than a psychotic cult leader with aspirations of world domination. Unlike more prominent antagonists in the franchise, he doesn’t really pose much of a threat beyond his fairly isolated community. In the end, Saddler has little impact on the franchise other than Las Plagas ending up on the global black market, and his TakeOverTheWorld attempt is far less successful than others. [[note]]Albert Wesker and Carla Radames were moments away from winning until the protagonists foiled their attempt, while Saddler hadn't even started his yet before he dies.[[/note]]

* WrongGenreSavvy: In the original game, Saddler mocks Leon's intention to save the President's daughter and stop his evil plan by claiming [[AmericaSavesTheDay "the American wins"]] is just a Hollywood cliché, and [[ThisIsReality he'll wake Leon up from his world of clichés]]. Their meeting ends with Leon blowing Saddler to kingdom come with a bazooka, and from there the rest of the game plays out like a Hollywood action movie: [[LoveInterestTraitor Ada betrays Leon for the sample]] but [[PetTheDog leaves him the keys to a jetski so he can escape]], Saddler's island [[CollapsingLair starts blowing up]] and Leon and Ashley narrowly OutrunTheFireball, Ashley flirts with Leon while they [[RidingIntoTheSunset ride off into the sunset]], and credits roll.

* AlasPoorVillain: His [[spoiler:death is portrayed much more mournfully in the Remake than the original, being framed as a MercyKill]] towards a long-broken soldier.
-->'''Krauser:''' ''...Do... what you have to do....''

* FreudianExcuse: In the remake, during Salazar's boss battle, he mentions that Leon reminds him of his father during the boss battle and later as he becomes more frustrated calls Leon a sickly, ugly half wit demon child that should be sent back to hell, as if he were reliving a confrontation he and his father had at one point.

* OmnidisciplinaryScientist: Researched the biology of the Plaga parasite (zoology), created a medication to suppress their growth in a host (pharmacology), developed a machine to kill adult parasites (biomedical engineering), and a weapon capable of killing parasites and hosts rapidly (weapons engineering).

* AdaptationalVillainy: Downplayed in the remake, as Salazar is already an unpleasant guy to begin with, but the memos you get across the castle implies that he's already an asshole in-and-out even before Saddler enters the scene and being infected with the Plaga, as opposed to the original where he was a lot more composed in the past.
